I was struggling to find a Green deck that I both enjoyed and that was effective in BO1. I was getting run over by Mono Red or shut down by control. Then I found what was like a bonus at the Harrahs casino, this list posted by batbosson Reddit.

Creature Spells:

4 Llanowar Elves (DAR) 168

4 Pelt Collector (GRN) 141

3 Silhana Wayfinder (RNA) 141

4 Growth-Chamber Guardian (RNA) 128

4 Kraul Harpooner (GRN) 136

4 Steel Leaf Champion (DAR) 182

4 Nullhide Ferox (GRN) 138

4 Ghalta, Primal Hunger (RIX) 130

Non-creature spells:

4 Adventurous Impulse (DAR) 153

3 Thrash // Threat (RNA) 229

Lands:

22 Forest (DAR) 269

The briliance of this deck is summed up by batboss in this one paragraph.

"The basic idea is to go bigger than the other aggro decks in the format, while still being fast enough to kill control before they can set up. You do not want to play against midrange, so I’ve found Bo1 to be well-suited to this deck because midrange is not very common."

Can one deck do all of that? Having played it now I can absolutely say, "Yes". You can go toe-to-toe in aggro matches due to your creature size, but you are still fast enough to win most matches versus control. I did run into some midrange decks that handled things well, but it could just as easily have been my piloting and not the deck.

Update: March 28, 2019

This deck doesn't fare especially well in the current meta. Alternative decks that are currently taking players to Mythic with 55% or better win rates are variations on:

Red Deck Wins - a creature based mono-red deck that uses runaway steam kin and burn cards to win before the opponent can get board presence.

White Weenie - a creature based, low mana cost deck that attempts to overwhelm the opponent early with boosted creatures. Benalish Marshall, Venerated Loxodon, skymarcher aspirant and history of benalia are all important cards in this deck.

Esper Control - a deck that attempts to limit the play of your opponent. This deck plays longer games, relying on removal, card draw and cards like Absorb to limit your opponents ability to gain board presence. Important cards include Search for Azcanta, Absorb, Vraska's Contempt, Kaya's Wrath and Teferi, Hero of Dominaria.
